Where were the Avengers when New York was on the verge of being taken over by giant lizards?

I don't understand why fans treat shared universes as if they're rocket science. Where were they, you wonder? Doing something different and being somewhere else either as a team or individually. I don't see why a more detailed explanation beyond that. Plus, if the comics and cartoons can get away with that despite every single superhero operating in New York (something that has bugged me for years about Marvel btw), then I don't see why the MCU can't get away with it especially since there are currently, at least to our knowledge, no superheroes operating in NYC other than Spider-Man. It all makes sense.
